To all whom it may concern.

Be it known that I, HENRI VICTOR JULns' 'J TFRET, a-citizen of the French Republic,

and resident of .Neuilly sur-Seine', 'Seine,

France,have inventedcertain new and usev j V diagrammatically, and respectively in"sec= 'ful Improvements Relating to Engines or abl Motors, of which the 'followingjis a sp'e'oifi- I V vation in'a plane perpendicular to the pre ceding, adetail of the arrangements cation.

This lnvention relates to engines or motors and refers more particularly to those provided with crank shafts supported in 'cas-' ings, although the'invention may be adapted for other types of engines, where found suit- The object of the invention is to construct engines or motors of the type in question so that the placing of the crankshaft in position and its removal, and the construction of the casingwhichsupports the said shaft may. be effected more simply and in a more practlcal manner and consequently more eco- Jnomic'ally than hashitherto been the case.

The invention consists essentially in providing the crank shaft of the engine or motor with bearings adapted torest upon supports located in the casing, the upper portion of the bearings being provided with an extension; the vertical fpositionyof which is adapted be adjusted by appropriate means, such for instance as a screw. The casing is formed from a single piece and the device comprising the crank shaft and the attached bearings is inserted through an opening in the casing, so as to reston the said supports, after which'each screw is so adjusted that :it exerts pressure upon the wall I fully explained hereafter.

It also includes certain constructional embodiments'of the said arrangements, and as new industrial products engines of the class in question, with the arrangements applied thereto special parts suitable for the construction of such' motors; and automobile vehides and installations comprising such eng'ines.

In order that the invention may be clearly understood, it will now be described with I reference to the accompanying drawing, the

description and drawing being however e e yg l y eb Of i m the casing, a recess Figure :1 of the; drawing hows diagram atented Dec. 2t, 1921'.

I) is a "member adapted to constitute "the lower portion of the bearing for the boss 02, ofappropriate size, in which is provided in' 'a direction passing through the axis and the middle of the base '0, ahole d 1 "adapted to receivea screw threaded rod 6, "the upper end of which'is provided with a six sided extension or nut e and with a plain portion adapted to engage in a piecee 7 The piece 6 is extended on the outside into two projecting portions 6 opposite and parallel to one another. on to the rod 6.

' The crank shaft a is fitted betno en-any two of its cranks with bearing constructed' "as ustdescribed.-

' f-is a casing which is formed in a'sin'gle piece and-of a'slze suitable for" the reception of the crank shaft upon which the bearings have"been fitted;- This casing is provided with an openinginto which the shaft thus fitted canbe passed,;and with other openings for the passage of theconnecting rods when" the crank shaft is'in position. f are webs provided with openings concentric with the crank shaft and of a radius equal to the basec of each bearing,so that the edges of the openings serve to support the circular bases c of the bearings. "The edges are of a Y Where each of the pieces-e rests "against is provided correspond-- ing to the profile of'the pie'cefe v I f It will be readily'understo d that if the screws eare turned into a position at which thicknesssubstantially equalto the distance between the projectionse of the pieces 6 the extremities of the projections e are at a distance from the axis of the crank shaft slightly less than the distance of the said axis from the edges of the recesses itis possible, after having passed the crank shaft into the opening in the casing to pass it through the openings in the webs f and then to rest the lower edges of the hearings on the edges of the webs intended to support them. When this has been done, the screws 6 are turned so as to press the piecesc toward the recesses. The edges of the recesses engage the projections e and the screws are turned to the desired extent. Finally the nut e? in each bearing is screwed against the boss 03.

It is to be understood that the fitting up of the crank shaft may be completed, by supporting its extremities by means of bearings 7, which may be identical with those already described, openings in the casing adapted to receive them being provided for 7 that purpose.

What I claim as my invention and desire to secure by Letters Patent of the. United States of America is 1. In combination a crank case, a web in said crank case having an aperture therethrough, a crank shaft, a bearing surrounding said crank shaft provided with extensions, said bearing and extensions being freelyinsertible within the aperture in said web, ad ust1ng means cooperable directly with one of sald extensions for forcing said extensions into clamping engagement with the periphery of the aperture in said web.

2. In combination a crank case, a web in saidcrank case having an aperture therethrough, a crank shaft within said crank case. a bearing on said crank shaft, said bearing having an integral extension on one side thereof freely fitting said aperture and an extension on the other side thereof havinga radially movable portion freely fitting said aperture when in retracted position, a-dpistlngmeans carried by said bearing and V constructed to force said integral and movable -extension's into clamping engagement with the periphery oftheaperture in said web.
